Information About Basic BGP

Cisco NX-OS supports BGP version 4, which includes multiprotocol extensions that allow BGP to carry
routing information for IP multicast routes and multiple Layer 3 protocol address families. BGP uses
TCP as a reliable transport protocol to create TCP sessions with other BGP-enabled devices.
BGP uses a path-vector routing algorithm to exchange routing information between BGP-enabled
networking devices or
to reach a particular destination while detecting and avoiding paths with routing loops. The routing
information includes the actual route prefix for a destination, the path of autonomous systems to the
destination, and additional path attributes.
